Pomegranate’s hidden fiber-bound polyphenols significantly increase total antioxidant capacity

Researchers showed that pomegranate fruit extract contains substantial levels of non-extractable polyphenols bound within its fibre-rich matrix, significantly increasing its total measured antioxidant capacity. In human neuronal and astrocytic cell lines, the extract reduced hydrogen peroxide–induced oxidative stress, particularly in astrocytes, under in vitro conditions.

Smoking triggers epigenetic damage linked to macular degeneration

Through a series of experiments supported by the National Institutes of Health, Johns Hopkins Medicine (JHM) researchers say they have advanced understanding of how smoking damages the eye and contributes to the development of age-related macular degeneration (AMD), the leading worldwide cause of visual impairment and blindness among people 50 and older.

Genetic switch MafB enables macrophages to reach full maturity and preserve organ health

Researchers at the University of Liège have identified a key genetic regulator that enables macrophages to reach full maturity and preserve the health of our organs.

Immune cells shape maternal and infant health during lactation

It's widely known that breastfeeding impacts the health of both mother and child, but the underlying biology that leads to these effects has been understudied.

Neanderthal DNA loss tied to ancient interbreeding dynamics

The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia.

Jumping DNA fragments found to destabilize cancer genome

A study published today in the journal Science reveals how jumping fragments of human DNA, a type of genetic parasite, destabilise the cancer genome. Unstable genomes are a fertile playground for cancer evolution, giving malignant cells more opportunities to grow, adapt and evade treatment.

Microbial cities in space: Risks and opportunities for astronauts

A global team of scientists has identified an often-overlooked biological system - biofilms - as a critical factor in the future of human space exploration.

Identifying the core catalyst for muscle energy production

Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this mechanism works.

New study refines the limits of brain mapping

When removing cancerous tissue in the brain, neurosurgeons often use "awake brain mapping" to minimize the risk of causing unintended disruptions to a patient's quality of life while removing as much tumor as possible. This practice, which has been used for decades, involves waking a patient up mid-surgery to test their neurocognitive functions in real time by stimulating the brain surface and assessing for functional changes.

New daily tablet simplifies long-term HIV care

A new, daily oral tablet that combines two current HIV treatment medications, bictegravir and lenacapavir (BIC/LEN), may be able to effectively replace more complicated HIV treatment regimens used by people living with HIV who are long-term survivors, according to the results of a new phase 3 clinical trial published in The Lancet.

Study reveals hidden internal structure within biomolecular condensates

Cells rely on biomolecular condensates to coordinate essential biological processes without surrounding membranes.

Long-term cola intake weakens immune cell counts in controlled rat study

Replacing drinking water entirely with sugar-sweetened or sugar-free cola for eight weeks altered gut microbiota composition and immune-related indices in rats, despite no changes in body weight or blood glucose. Both beverages were associated with leukocyte reductions and organ-related biochemical shifts, with sugar-sweetened cola more strongly linked to renal markers and diet cola to elevated liver enzymes.

Could a rare gene variant help reduce smoking? New study suggests it might

An exome-wide association study of nearly 38,000 smokers from the Mexico City Prospective Study identified rare coding variants in CHRNB3 that are associated with substantially fewer cigarettes smoked per day. Cross-ancestry analyses in European and East Asian datasets support a role for the β3 nicotinic receptor subunit in modulating smoking intensity.

Unexpected behavior observed during interactions between immune cells and dying cells

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm by a robust nuclear envelope.
